In this model, there is a vicious cycle of events that results in the generation of a more and more repressed state. One of the predictions from this model is that repressive histone modifications attract DNA methyltransferases, which deposit DNA methylation near those histones. This methylation in turn attracts more repressive histone modifying enzymes, creating a self-perpetuating cycle that leads to an increasingly hostile region for gene expression. Experimental data suggest that in many cases this model seems to be right. Repressive histone modifications can act as the bait to attract DNA methylation to the promoter of a tumour suppressor gene. A key example of this is an epigenetic enzyme we met in the previous chapter, called EZH2. The EZH2 protein adds methyl groups to the lysine amino acid at position 27 on histone H3. This amino acid is known as H3K27. K is the single letter code for lysine (L is the code for a different amino acid called leucine). — Nessa Carey

Obviously, everybody's favorite form of web content is more story with principal actors. But the economics of the web do not yet support. — Matt Nix

Maybe after you die you get sent to a giant room with archives of newspapers that have been written by these angel journalists specifically about your life and then you read them and they look like this. That would be insanely depressing. Hopefully at least some of her headlines would be about the other people in your life and not just you. — Jesse Andrews

The fact is that while there has been a good deal of discussion for and against women in business, farm women have always been business women, and I have never heard a protest. — Laura Ingalls Wilder

You can always improve your situation. But you do so by facing it, not by running away. — Brad Warner

The results suggest a helical structure which must be very closely packed containing probably 2, 3 or 4 coaxial nucleic acid chains per helical unit and having the phosphate groups near the outside. — Rosalind Franklin

The McEvoys, for their part, apparently had two dominant founding Y chromosomes, a theory that is supported by records revealing that when the name was anglicized, two ancient families, the Mac Fhiodhbhuidhes and the Mac an Bheathas, were drawn in under the same banner and both became McEvoys. History also indicates that fully three Irish surnames - McGuiness, Neeson, and McCreesh - are all anglicizations of the same Gaelic name Mac Aonghusa (son of Angus), which DNA evidence confirms, as all three groups overlap strongly on one Y. — Christine Kenneally

An oligarchy of private capital cannot be effectively checked even by a democratically organized political society because under existing conditions, private capitalists inevitably control, directly or indirectly, the main sources of information. — Albert Einstein

In its quest to organize the world's information, Google has scoured vast troves of data to amass the greatest accumulation of information assets on the planet, including the billions of search queries on google and YouTube and the billions of interactions on Android, the dominant operating system for most mobile devices. Google also controls an ever-growing index of the world's websites and the browsing history of more than 2 billion users, three types of maps of the Earth's surface and traffic patterns, a real-time list of trending topics, the largest archive of discussions in Usenet groups, the entire contents of 20 million books, a huge collection of photographs, the largest collection of video on the planet, the largest online email repository, even the largest archive of DNA data. — Robert Tercek
